Daniel Vena

Daniel Vena is a PhD candidate with the University of Toronto doing research at the University Hospital Network – Toronto Rehabilitation Institute (UHN-TRI) on preventing the effects of fluid shift on sleep apnea. Fluid that accumulates in the legs during the day (due to sedentary lifestyle) has been shown to increase overnight shift of fluid from the legs into the neck where it accumulates and can increase the severity of sleep apnea. Daniel is experimenting with the use of electrical stimulation of the calf muscles to reduce the accumulation of fluid into the legs to effectively reduce the shift of fluid from the legs into the neck and alleviate sleep apnea.
